Frederic Barrat cce84fc919 pnv/xive2: Add definition for TCTXT Config register 
Add basic read/write support for the TCTXT Config register on P10. qemu
doesn't do anything with it yet, but it avoids logging a guest error
when skiboot configures the fused-core state:

qemu-system-ppc64 -machine powernv10 ... -d guest_errors
  ...
[    0.131670000,5] XIVE: [ IC 00  ] Initializing XIVE block ID 0...
XIVE[0] - TCTXT: invalid read @140
XIVE[0] - TCTXT: invalid write @140
